What would be the best place to use PEEK? As someone who’s experimented with super tough polymers in 3D printing, where would the self-lubricating/low friction plastic be best used? My instinctual thought is bearings + chainrings. Does anyone else have ideas?
disclaimer. i’ve just googled peek for the first time and read the first hit.
There used to be a product available which was marketed as a lightweight replacement for the upper headset bearing, IIRC it was a solid “nor-glide” bushing/plain bearing which dropped directly into a normal headset and saved a few grams.
Nobody really cares for the few grams it saved (at least not anymore, though we did at the time) , and apparently they were a bit sticky and hard to preload perfectly.
However, we’re currently having a new crisis of identity and rather than picking grams we’re trying to ram all the cables through the upper headset bearing to keep them out of the wind.
Would a PEEK “replacement bearing” be a viable option in that it could take up substantially less room or have gaps for cables (space REALLY is at a premium in there) , and potentially not be a fixed full ring? if it had a split in it or was two halves , it could REALLY save some servicing Pfaff.
